### Optical Field of View Explanation
#### Fixed Focal Length Thermometers
- **Fixed Focus**: The focus of fixed focal length thermometers is predetermined and non-adjustable. Accurate temperature measurement is only achieved when the target is at the specific focal distance designed into the instrument.
#### Adjustable Focal Length Thermometers
- **Adjustable Focus**: With adjustable focal length thermometers, the focus can be modified by the user, allowing for accurate temperature measurements at various distances within a specified range, all while maintaining the designed distance-to-spot ratio.
- **Focus Adjustment**: Users can alter the focal distance by rotating the optical lens, enabling them to achieve the optimal measurement size from an appropriate installation location.
- **Laser Targeting**: By using the targeting laser and observing where the laser spot is smallest and most distinct, users can determine the precise measurement focus of the thermometer.
#### Measurement Calculation
- **Measurement Calculation**: Assuming a measurement distance of L and a thermometer with a distance-to-spot ratio of, for example, 200:1, the measurement diameter M at that distance can be calculated as $ M = \frac{L}{200} $.
#### Example
- **Example**: If the measurement distance $ L $ is 4 meters and the thermometer has a distance coefficient of 200:1, then the measurement diameter $ M $ would be 20 millimeters.
#### Additional Notes
- **Temperature Measurement Threshold**: The minimum measurable temperature of the target should be at least 25°C above ambient temperature. For a measurement accuracy of 50°C, the response time is approximately 1 second.
This explanation provides a clear understanding of the optical capabilities and usage considerations for fixed and adjustable focal length thermometers, ensuring accurate temperature measurements in various applications.
